Watch Jimmy Fallon’s Awesome Theme Song Medley

It's another Jimmy Fallon musical masterpiece. This time he joins the cast of the new NBC show 'Guys With Kids' to celebrate the lost art of the TV theme song...by singing a four-minute medley of some of the greatest themes of all time. Added bonuses: audience singalong (naturally) plus a 'Mary Tyler Moore' freeze frame. Can you name every theme song?
